Abstract The thermal relaxation time for a chemically non-equilibrated gluon plasma is calculated using the non-equilibrium Debye mass as the infrared regulator. The dependence of the thermal relaxation time on the fugacity is given. We find that there is a threshold fugacity λ _g^*. When λ_g < λ _g^*, τ ^NEQ/τ ^EQ decreases sharply with increasing fugacity, while λ_g > λ_g^*, the ratio is almost unchanged.
